      <p>An HTML-based inspector that displays and allows editing of data for the selected Part (if any),
        or for a particular JavaScript object, or for the shared <a>Model.modelData</a> object,
        which exists even if there are no nodes or links.

      <p>The inspector code lies in <a href="DataInspector.js">DataInspector.js</a> and <a href="DataInspector.css">DataInspector.css</a>. This code is meant to be a starting point for making your own model data inspector.

      <p>On browsers that support it, color types display a color picker. There are various plugins and polyfills for this functionaltiy if you wish to extend the data inspector.

      <p>
        This shows the contents of the model after each transaction:
